TlME-INDICATING DEVICE.

SIEOIFIOATION forming part of Letters Patent No. 657,167, datedSeptember 4, 1900.

Original application filed December '7, 1898, Serial No. 698,610.Divided and this application filed September 25, 1899. Serial No.731,647. (No model.) I

698,510, and for which I have made applica.

tion for Letters Patent in Great Britain under No.20,754, dated October1, 1898; in Germany, dated November 22, 1898, and in France under No.279,115, dated July 24, 1899,) of which the followingis a specification.

This invention relates to time-indicating devices, and has for itsobject the arrangement and construction of a simple mechanism whereby aclock or timepiece is adapted to record on separate dials or facesprovided with hands or other indicators the time or the sum of the timesoccupied by a certain operation or series of operations, the mechanismbeing so arranged as to enable any dial or face to be immediatelyconnected with or disconnected from the clock or timepiece at the willof the operator.

This device is particularly applicable for such purposes as recordingthe time occupied by any piece of work, whether performed at one time orin several portions, or by recordingthe time a telephone is in use, aclerk is employed in his writing, a speaker is addressing an audience,or a chemist or other operator is engaged in a laboratory process orexperiment.

To carry my invention into effect, I take any ordinary clock ortimepiece and I attach to it externally a cog-Wheel or other gearconnected with the minute or hour hand mechanism of such clock ortimepiece. To the clock or timepiece I attach a frame or othersupporting device adapted to support one or more dials or faces havingtime divisions. I provide each dial or face with a hand or hands orindex driven by a cog-wheel, wheel, or other gearing attached thereto,and I adapt each dial with its accompanying hand or hands and gearing toslide or move upon the supporting-framework radially to or from thecog-wheel or other gear upon the clock, so as to engage with and bedisengaged from the gearing of the clock at will.

In order that my invention may be the better understood, 1 willnowproceed to describe the same in relation to the drawings hereunto 5 5annexed, reference being had to the letters marked thereon, like lettersreferring to like parts in the various figures.

Figure 1 is a front elevation of my timeindicating device. Fig. 2 isaback elevation of the same. Fig. 3 is a detail view of the slidingsleeve carrying the indicating-dial and gear-wheels. Fig. 4 is asectional view of the same.

Referring to Figs. 1 and 2, it will be seen that the frame A, which maybe of any suitable form, but is here shown cruciform, is attached to theback of the clock B, provided with the cog-wheel E, connected with theminute 01' hour hand mechanism, and that each dial 0 and its gearing Kis mounted upon a sleeve D, adapted to slide radially to or from thecog-wheel E upon one of the radiating arms of the frame, so as to becapable of being moved relatively to the clock with great facility. Itwill be seen from Fig. 2

that the four upper dials are disengaged from and the two lower dialsare engaged with the cog-wheel E of the clock B. I providememorandum-tablets F upon the frame adjacent to the dials O 0, uponwhich any given fact can be recorded which may have reference to theparticular dial adjacent to it. The sleeveD is provided with aspring-tongue having a projection G, which is adapted to engage intoeither one of the holes 11 in the arms of the frame, so as to maintainthe wheels in or out of engagement, as circumstances require. Aplurality of separate and independent operations can be timed by thisarrangement.

Having now particularly described this invention, what I claim, anddesire to secure by Letters Patent, is-- A time-indicating deviceconsisting of a timing mechanism, in combination with a cruciform frame,a sleeve on each arm of said frame and adapted to slide thereon, a dialcarried on said sleeve, an indicator for said dial, and gearing mountedon the sleeve for operating the indicator, whereby any set of gearingcan be engaged with the timing mechanism by sliding its sleeve along thearm.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
